Acetylene, ${\mathrm{C}}_2{\mathrm{H}}_2$, can be converted to ethane, ${\mathrm{C}}_2{\mathrm{H}}_6$, by a process known as hydrogenation. The reaction is The equilibrium constant of a system, $K$, can be related to ${\mathrm{C}}_2{\mathrm{H}}_2(\mathrm{g})+2{\mathrm{H}}_2(\mathrm{g})?{\mathrm{C}}_2{\mathrm{H}}_6(\mathrm{g})$ the standard free energy change, $?G^{?}$, using the following Given the following data at standard conditions (all pressures equal to $1\mathrm{atm}$ and the common reference temperature $298\mathrm{K}$ ), what is the value of equation: $K_{\mathrm{p}}$ for this reaction? $?G^{?}=?RT\ln K$ where $T$ is a specified temperature in kelvins (usually $298\mathrm{K}$ ) and $R$ is equal to $8.314\mathrm{J}/(\mathrm{K}?\mathrm{mol})$. Under conditions other than standard state, the following equation applies: $?G=?G^{?}+RT\ln Q$ In this equation, $Q$ is the reaction quotient and is defined the Express your answer using two significant figures. same manner as $K$ except that the concentrations or pressures used are not necessarily the equilibrium values.
